Thank you for the response i tested my urine for proteins a year ago all was fine then. I also am normal weight 6'3 male and pretty active in the gym/sports....I just don't know why I have it. My top number is the one I have trouble with (systolic) I did a stress test two years ago and they said all was fine but what was weird was they didn't take my Bp other than just before it...my stress test ran about 9 1/2 mins...
Risks of what? Kidney damage from high blood pressure? Sudden cardiac death?
For the latter, I think a supervised stress test (treadmill + ECG) is very good (of special interest is your heart recovery rate after high exertion, by comparing the endpoint heart rate with that at the one and two minute points during recovery).
Kidney damage is impacted by your average blood pressure being dangerously high, short duration spikes ought not influence that. That said, I think it's prudent to have urine testing for protein in urine from time to time (part of annual physical?), as I think it's presence may be a clear sign the kidneys are starting to fail (or are coping with an infection or both).
It's not quite that simple though. Narrowing of the arteries chloresteral (a cause of high blood pressure) might first impact the kidneys (before notably high BP measurements occur), and restricted blood supply to the kidneys can lead to serious kidney problems (renal hypertension).
A healthy weight and lifestyle (activity/diet), can be very helpful towards keeping arteries more open (reducing risks of high blood pressure).
